iMPROVEMENT IN PLANlNG-MACHINES.

Specification forming part of Letters Patent No. 161,749, dated April 6,1875; application filed September 18, 1874.

To all whom it may concern:

Be it known that we, CHARLES and GEORGE F. BUss, of Marlborough,Cheshire county, New Hampshire, have invented an Improvement inPlaning-Machines, of which the following is a specification The drawingsaccompanying this specification represent, in Figure l, a sectional sideelevation; Fig. 2, a sectional end elevation; Fig. 3, horizontal sectionof feed; Fig. 4, side elevation of one of the headrails and endstandards.

in these drawings the main frame is shown at A as composed of endhousings or standards B B, united at bottom by horizontal girts G O, andat top by rails, the girts or lower beams O 0 being triangular incross-section, as represented, by which we economize space, and obtainample room for access to the lower part of the machine, and leave thefeed-apron unobstructed. The cutter-head of the machine is shown at E,and two pressure-rollers, which bear the material to be planed down uponthe feed-apron, at F G, these parts being arranged in manner similar tomachines now in use. H H represent two horizontal rails or carriages,disposed between the housings B B, and immediately adjacent to thelatter, the purpose of these bed-rails being to support the movable bedor endless apron I, which travels over them, and supports and bearsalong the board or other object to be planed. Each rail H H is supportedas follows: Upon the inner face of each housing B B we cast two uprightguides or ribs, to a, each of which is undercut or dovetailed, and thetwo receive each a bar, b, cast upon and depending from the under sideof each bed-rail, the guides at a and bars Z2 Z1 constituting ways andslides by which the two rails and the endless apron are raised andlowered with respect to the cutter-head E. Through each bar b we screwseveral set-screws, K K, which bear at their inner ends against a plateor block, d, inserted between them and the adjacent rib or guide a,these screws and plates serving to of fectually prevent looseness andtrembling of the bed-rails and apron, while the ribs to, bars I), andplates (1, constitute a powerful and unyielding support to saidbed-rails and apron. In order to raise and lower the bed-rails H H, wescrew through the lower part of each an upright screw, L, which ismounted at bottom in a shelf, f, cast upon each housing, the lowerextremity ofthis screw carrying a worm gear, g, which is engaged anddriven by a worm, h, affixed to a horizontal shaft, 41, extendingtransversely of the machine below the feed-apron, the outer end of thisshaft being rotated directly by a crank or band wheel, or by anysuitable mechanism.

The central portion of the upper part of each bed-rail is faced with aplate, j, of hardened steel by which its wear is greatly prolonged, anda smooth finished surface is always presented.

- The mechanism for feeding the endless apron, and the stock to beplaned, is as follows: The shaft which carries the forward pair ofsprocket-wheels for feeding the apron is shown at l as carrying at oneend a spurgear, m, while engaging this gear and rotating it, and theshaft is a pinion, 10, mounted upon a second shaft, 0, in rear of andparallel to the shaft l, this latter shaft 0 being in turn provided witha spur-gear, p, affixed to its outer end, which gear meshes into and isdriven by a pinion, q, making part of the hub of a pulley of the feedmechanism.

The feed mechanism thus organized is very poses stated.
